Liquid Level Indicators

Liquid level indicators, also called fluid level indicators, are specialised devices designed to visually monitor and measure the levels of liquid in tanks, vessels, or other containers. These devices provide real-time feedback to ensure the liquid levels stay within safe or desired ranges. These fluid level gauges offer a visual or automated indication of the liquid’s height and quantity to avoid overflow, monitor tank levels, and ensure efficient operations across various hydraulic systems and applications. 

Why Buy Liquid Level Indicators?

Purchasing a liquid level indicator is crucial for several reasons. They ensure the prevention of overfilling or running dry equipment, which can lead to spills or equipment damage. A liquid level gauge maintains accurate, consistent monitoring of fluid levels, improves system efficiency, enhances safety, and reduces costly mistakes or accidents. In essence, using a quality hydraulic level indicator helps streamline industrial operations and improves overall productivity. 

View Our Best-in-Class Liquid Level Indicators:

We offer the following types of liquid level indicators to suit your needs and preferences. Our selection includes:

  • Column Level Indicators – A column level indicator is a device designed to offer a direct, visual reading of the liquid height, typically mounted externally to the tank. These indicators are easy to install at the top and bottom of the transparent tanks and vessels.
  • Sight Glass Level Indicators – Similar to column indicators, sight glass indicators use a robust glass tube or integrated window to provide a direct visual indication of the liquid level. They are equipped with protective shields for added safety and are ideal for chemical, food, and beverage industries where visibility is critical. 
  • Plug Level Indicators – Plug level indicators, also called magnetic liquid level indicators, are simpler devices often used for spot checks or in smaller tanks. They offer an easy and effective way to monitor liquid levels in tanks with limited access. A plug level indicator is also handy for scenarios where other types of indicators might be difficult to install.
  • Temperature & Level Indicators – A temperature and level indicator is a combined indicator that offers dual functionality, monitoring liquid levels and temperatures in tanks or pipelines. 

Typical Uses of Liquid Level Indicators:

Fluid level indicators are used in a variety of industries, including:

  • Chemical Manufacturing
  • Water Treatment
  • Oil & Gas
  • Food & Beverage
  • Pharmaceuticals
  • HVAC Systems
  • Industrial Processes
  • Automotive
  • Medical Equipment.
